From full rotation into linear motion: Rack and pinion drives with synchronous servo motors.
With the innovative system concept for rack and pinion drives, STOBER has developed a compact, easy-to-use system with process reliability that is precisely tailored to the application areas of machine tools, automation and robotics.
By combining them with our planetary or helical bevel gear units and STOBER servo motors, you get the benefit of extremely compact, highly dynamic drive solutions.
Our rack and pinion drives are versatile, ready-to-install solutions that are adapted to meet the various requirements in terms of load capacity and precision.
All pinion designs are available in combination with STOBER planetary gear units, and the ZV series can also come with helical bevel gear units.
Optimal: All STOBER EZ series motors can be directly attached to the gear unit in any size you need – without any adapters.
Omitting the motor adapter means that you benefit from lower mass moments of inertia so you get the most out of the dynamics of your drive.
ZV…EZ: High flexibility for automation and robotics
Rack and pinion drives from the ZV series mean maximum flexibility when it comes to possible combinations.
The rack and pinion drives can be mounted either on the planetary gear units from the P series, on the very economical PE series or
on STOBER helical bevel gear units from the K, KS or KL series.
No matter which drive solution you require, you will always benefit from a perfectly matched, powerful geared motor equipped with top-quality helical gearing.
ZR…EZ: High speed due to high feed velocities
The rack and pinion drives of the ZR series feature large, helical pinions with a bolt circle, which allow high feed velocities.
By combining them with a PH series planetary gear unit and an EZ series synchronous servo motor, you get a high-performance geared motor ideal for any kind of drive solution with the highest requirements for rigidity, precision and reliability.
ZTR…EZ: High performance for demanding drive concepts
The very precise and also very powerful ZTR series features small pinion diameters and high linear rigidity and requires lower torques.
The pinions with the welded screw flange can be easily mounted and dismounted. The ZTR series is therefore ideal for feed axes of machine tools where the supporting bearing holder is an interfering contour. This means gantry machines, vertical and horizontal lathes or milling and drilling centers.
By combining the series with PH or PHV series planetary gear units and an EZ series synchronous servo motor, you get a high-performance geared motor ideal for any kind of drive solution with the highest requirements for rigidity, precision and reliability.
ZTRS…EZ: High force for maximum power density
Developed by STOBER, the bolted supporting bearing holder with stiffening ribs on the inner contour makes it possible to use the full gear torque in a rack and pinion drive for the first time. This also optimizes the power density and rigidity.
ZTRS is ideal for feed axes of machine tools, laser machines and highly dynamic and precise handling systems.
By combining the series with PH, PHV or PHQ series planetary gear units and an EZ series synchronous servo motor, you get an extremely compact, highly dynamic drive with STOBER’s typical top-quality helical gearing and very high torsional and tilting stiffness.
